Minor planet 16 Psyche

This photo is made from a sequence taken at 4 minute intervals for just over an hour. The rather odd appearance of the trail was due to the planet passing very close to a star near the beginning of the sequence. I verified that by looking at the individual frames.

The blobby nature of the trails is because the early images in the sequence were taken more frequently than every 4 minutes. The processing was done with GRIP's semi-interactive option "Astro combine for comets" on the batch menu. That option is equally useful for most small objects that move relative to the stars.
